L79L15AC集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

L79L15AC屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團制造生產(chǎn)的L79L15AC穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。

The L79L00 series of three-terminal positive regulators employ internal current limiting and

thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided,

they can deliver up to 100 mA output current.

They are intended as fixed voltage regulators in a wide range of applications including local or

on-card regulation for elimination of noise and distribution problems associated with single-point

regulation. In addition, they can be used with power pass elements to make high-current

voltage regulators.

The L79L00 series used as Zener diode/resistor combination replacement, offers an effective

output impedance improvement of typically two orders of magnitude, along with lower quiescent

current and lower noise.
